The document describes AirQUEEN Nano Mask and its nanofiber filter. It notes that the nanofiber filter has better permeability and blockability than other filters due to its thin 1 nanometer fibers. The nanofiber filter allows for easier breathing compared to other masks. It also details that the nanofiber filter is produced through a patented process and in an ISO-certified clean facility, and has received approvals from European SGS, REACH, and RoHS certifications, showing it is safe. The document promotes the AirQUEEN Nano Mask as a breathable option that is important for all-day use and for sensitive skin.

3. Breathing New Technology, Nanofiber
Permeability Blockability Durability
Nanofiber FilterNano fibers are only 1 nanometer, 1 billionth of a meter, in thickness
Nanofiber is a new material made by building these fibers sterically for a
fishnet structure that has better permeability, blockability, and
durability than any fiber ever invented.

6. Because it touches the nose and the mouth,
this fiber is very appropriate for masks where
permeability is important
[From interview with professor Kim Iksu of Department of Textile atShinshu
University, Japan]
We asked professor Kim Iksu, the most renowned professor in the fiber research area.
What kind of material isNanofiber?
The thickness of a nano fiber is only a thousandth of a strand of hair.
Nanofiber is a material made by building these fibers sterically for a fishnet structure, and
nanofiber of 85% processing rate has both permeability and blockability.
The Nanofibers have consistent thickness and pore size.
This means the ratio of the pores in the general area becomes very high, which
is relevant to permeability.

8. Long-lasting freshness
from morning to evening!
The effectiveness of electrostatic masks decreases with each breath due to the moisture
Nanofiber Filter has great permeability, so you can feel fresh even after a long term use

9. Nanofiber smart filter
blocks pollutants and enables easier breathing
Excellent filtering and
permeability of Nanofiber

10. If you care about the skin,
permeability is even more important.
There is moisture in our respiratory system
If a mask has bad permeability, the moisture from within
cannot escape, which causes eczema
If you wear a mask for a long time,
you really need a permeable mask
Wearing mask all day causes skin trouble
